Last things first, you can't see the code ever from within c2 environment (as much as I know, that is). Maybe it's possible to view it from outside, after it's been changed to html5, but I'm not sure about it either. And in time you actually notice what you do inside c2 is the code and you forget the need to see it. I know because I came from XNA and currently I don't find anything I can't do with it. (Except 3d and per pixel data read on sprites, which is actually possible and has been done in C2, it's just that "I" can't do it.)
The code you want is pretty easy, though;
While a condition is selected press "b" to create a sub event. Then do it one more time, thus you would have two sub events.
In the first sub event enter condition 1 and do whatever you want
In the second sub event, press x first to make it an "else" event, then enter your condition 2.
You can repeat the process as much as you want. This is actually an if-else if chain statment.
See you around
